Abstract

A process is described for producing thin crimped tows from LOY, POY, or FOY filaments in a total linear density from 2 ktex to 9 ktex by filament yarns being withdrawn from creeled bobbins, folded and provided with a processing finish, then drawn or tension-uniformized and thereafter heated and stufferbox crimped. The process can be carried out in-line with numerous further processing operations. The tows are particularly useful for producing textile hygiene articles such as diapers, sanitary napkins, inserts and incontinence guards and the like.
